Otherwise require you to run a cable from the bother board to the video card. It's usually two wires that look like small square pegs about a centimeter tall and 2 millimeters thick. Also, you have to set your default playback device in Windows. I don't know how to do this in Windows 7. In XP, I used to do this and use the TV for videos off my computer. GOM player had the ability to redirect the sound to a different sound card, so I had the integrated sound going to the TV speakers, and the sound card sound going to the computer speakers. This allowed me to have two audio tracks playing at the same time without overlapping.
